He actually doesn't have any PS-1s (as per Most Wanted).
I do, however. I haven't listened to them in a while. Every time I am tempted to put them up for sale, I listen to them and talk myself out of it. Feel free to make me an offer anyway, I could be tempted.
I should go listen to them. I could buy a Rhodes or something with the money, or down payment on a new car.
Back to the topic -- I had a pair of HP-2s that I was going to send in to him -- mostly because of a channel imbalance. So there are perfectly legitimate reasons to want them refurbished.
But I lost them.
